3,013,712 RECLQSABLE TEAR-STR@ CARTON Kenneth Il. Woilaeger, Cincinnati, Uhio, assigner to Diamond National Corporation, New York, N.Y., a corporation of Delaware Filed May 3, 1960, Ser. No. 26,476 4 Claims. {(Il. 229-51) This invention relates to a carton construction. More particularly, this invention relates to a tear-strip carton.

An object of this invention is to provide a tear-strip carton in which, when a tear-strip is removed, a cap is formed which can be replaced and reused. i

A further object of this invention is to provide a tearstrip carton havingV a double wall and in which the outer wall is divided by the tear-strip into a cap portion and a lower or main portion, and in which the inner wall serves to strengthen the carton and in which the upper part of the inner wall forms a guide or support for receiving the cap portion.

A further object of this invention is to provide a tearstrip carton of this type which can be folded at for ready shipment and which can lbe erected and filled by means of conventional filling machines.

The above and other objects and, features of the invention will be apparent to those skilled in the art to which this invention pertains from the following detailed description, and the drawings, in which:

FIG. 1 is a plan View of a blank from which a carton constructed in accordance with an embodiment of this invention is formed, score lines being indicated in dash lines.

IG. 2 is an enlarged plan view of the blank folded to a first folded position;

FIG. 3 is a plan View showing the blank further folded, a portion of one panel being broken away to reveal internal construction;

FIG. 4 is a plan view of the carton in shipping position;

FlG. 5 is a perspective view showing the completed, filled carton, a tear-strip thereof being shown partly released;

FIG. 6 is an exploded view showing the carton after removal of the tear-strip;

FIG. 7 is a view in section taken on the line 7-7 in FIG. 6; and,

FIG. 8 is a view in section taken on the line 3-8 in FIG. 5.

in the following detailed description, and the drawings, like reference characters indicate like parts.

In FIG. 1 is shown a blank 9 from which a carton constructed in accordance with an embodiment of this invention is formed. The carton includes a main portion 19 of paperboard or the like to which a strip 12 of strong tape is adhesively attached. The strip of tape can be of any suitable tear-strip material and it can include lengthwise threads or filaments or the like to impart strength. The blank is cut to the shape shown in FG. 1 and is provided with score line-s as indicated in dash lines. Transverse score lines 1e, 15, 16, 17, 18, 19, 20, 21, and 22, divide the blank into an inner front panel 2a, an inner side panel 26, an inner back panel 27, an inner side panel 28, an inner glue panel 29, an outer glue panel 31, an outer side panel 32, an outer rear panel 33, an outer side panel 34, and an outer front panel 36. Upper and lower tabs 37 and 38 are hinged to ends of the outer side panel 32 at score lines 39 and 41 respectively. Upper and lower tabs 42 and 43 are hinged to ends of outer side panel 34 at score lines d4 and t6 respectively. Upper and lower closure flaps 47 and 43 are hinged to opposite ends of the outer rear panel 33 at score lines 49 and 51 respectively. Upper and lower closure flaps 52 and 53 are hinged to opposite ends of the outer front panel 36 along score lines 54 and 55 respec- 3,913,712 Patented Dec. 19, 1961 ice tively. Score lines 56 and 57 are provided along opposite sides of the tear-strip 12 and extend crosswise of panels 31, 32, 33, 3ft, and 36. End portions 58 and 59 of the score lines S6 and 57, respectively diverge to form a tab at one end thereof where the diverging end portions of score lines intersect an edge 60 of the outer front panel 36. A slot 61 is formed in the linking and glue panel 31 which intersects the tear-strip 12 dividing the tear-strip 12 into sections 12a and 12b.

In assembly of the carton the blank can rst be folded along the score line 18 (FIG. l), to fold the carton to the condition shown in FIG. 2 in which each inner panel is in registry with one of the outer panels. Glue strips 63 and 64 are rolled onto the glue panels 31 and 29 as indicated by stippling in FlG. 2., the glue strip 64 extending onto both the panel 31 and the panel 29. The inner front panel 24 is then folded, as shown in FIG. 3, to bring an edge portion 62 thereof into registry with the slot 61 in the glue panel 31 and with a section of the inner glue panel 29 where the edge portion 62 of the inner front Wall panel is attached to the glue panel 29 by means of adhesive on inner glue panel 29. The outer front panel is folded inwardly against the adhesive area on the outer glue panel 31 and attached thereto, to form the carton into the condition shown in FIG. 4. In this condition the carton is flat and can readily be shipped. The carton can be set up orl raised and filled in a conventional manner, whereupon the end tabs and closure aps may be folded inwardly and sealed to form a completed, iilled carton. In FIG. 5 the carton is shown in set up, filled position with the tear-strip j thereof started or partially released. The tear-strip is started by raising an end portion 66 thereof where the tear-strip intersects the edge 6i) of the front panel. The tear-strip can then be raised and removed to separate a cap portion 67 (see FIG. 6) of the carton from a main portion 68, as shown in FIG. 6. As shown in FIG. 6, upper portions ofthe inner panels 24, 26, 27, 28 and 29, form guides upon which the cap portion can be mounted for closing the carton for reuse. The portion 12a of the strip links these upper portions of the inner panels.

The carton construction illustrated in the drawing and described above is subject to structural modification without departing from the spirit and scope of the appended claims.
